Fans are excited for the upcoming return of "Reign" Season 4 on February 2017. However, some are saddened with the news that Adelaide Kane who plays the role of Mary Stuart will no longer reprise her role for season 5. Rumours had it that CBS Studios are already casting for the lead role.

According to some reports, "Reign" Season 4 will be the last project Adelaide Kane will do for the show. Will the 26 year old actress turn down season 5 for a major role in a movie? Because of reported news that Adelaide will be leaving the show, there are also rumours that CBS are already casting who will be the next Mary Stuart. As there has been no official statement from anyone in the cast and crew, fans should just wait and see and hope for the best.

Fans love the portrayal of Adelaide Kane with her role as Mary Stuart, the Queen of Scots. Now, should Adelaide Kane finally say goodbye to season 5, then fans will expect that Mary Stuart will die on the final episodes of "Reign" Season 4. Will viewers see Mary's head on a bucket? Will Elizabeth I (Rachel Skarsten) finally see victory?

"Reign" Season 4 will focus on the story of Elizabeth, according to some spoiler news. It will pick up from the death of Mary's husband, Francis of France (Toby Regbo) which will be the reason why the feud between the two cousins will become more intense.

On the other side of the coin, rumours were also filling the headlines that Rachel Skarsten's role as Mary Stuart's cousin in "Reign" Season 4 will be the last. If there's a grain of truth to that, Mary Stuart will continue to reign in the season 5.
